An Ingress Protection rating is a code that classifies and rates the degree of protection provided by an electric motor casing or enclosure against outside contaminants or “intrusion” that is published by the International Electrotechnical Commission. The IP code is a two or three-digit code that identifies the level of solid particle protection, liquid ingress protection and also any special circumstances about the motor such as oil resistance, weatherproof, etc. This is important information to know if you are getting an industrial motor repair or purchasing a new electric m
Motor bearings are a critical component of any electric motor, designed to consistently transfer loads from the shaft to the motor and support the rotor. The failure of these bearings typically result in expensive electric motor repairs. Here are some factors you should consider when selecting the best electric motor bearings: Speed The speed of the shaft directly impacts decisions you need to make about selecting the right kind of electric motor bearing. Some of the factors that need to be considered include: Lubricant used Size of the bearing Insulated or uninsulated? Cag
There are many electric motor repair shops out there, but how do you know which one is right for you? One method you can use to compare them is to look at the “in the field” services that they provide. Here are seven field services every excellent electric motor repair shop should deliver. Availability of Service – 24/7/365 Electric motors never seem to break down during normal, 9 to 5, Monday through Friday business hours. They break down at night, on weekends and over holidays. That is the reality of working with electric motors. They can break down at any time. And you need to h
Repair or replace an existing electric motor? This is the dilemma that all companies that use them faces from time to time. Both replacing and repairing electric motors is expensive, so how do you determine the best course of action when you find your electric motor out of operation? There are several factors you need to consider before making a decision and you need to gather the information about all of them before making the best choice for your operation. Was There a Bearing Failure? Bearing failures are a common problem with electric motors, and if a bearing failure occurs, it cause
We’ve already covered what a NEMA electric motor is in another blog post. NEMA stands for the National Electrical Manufacturers Association and is an organization that was created as part of the Energy Independence and Security Act of 2007 (EISA). The purpose of this organization is to improve motor efficiency in order to reduce the energy and operating costs for industrial, commercial and institutional buildings and, as a result, reduce the amount of electricity consumed by electric motors and reduce pollution. One of NEMA’s goals is make it easier for companies to manufacture elec
Because electric motors are used for many different applications and in so many different environments, the number of electric motor repair problems you might encounter may seem limitless, but in fact they tend to break down into several distinct categories: Blown Fuses or Tripped Circuit Breakers These are the most common problems encountered and the easiest ones to fix. Simply flip the breaker or change the fuse and you are back in action. Contamination Another extremely common problem is damage caused to the electric motor by contamination of some sort. Contaminants such as dirt, gr
All in all, electric motors are some of the most reliable equipment around. They are used in almost every environment, including some very extreme environments. As a result, they can be damaged by getting contaminated by dirt, moisture, oil or grease. They can be installed incorrectly, mishandled, or even run in conditions that go beyond what they were built for. These situations can impact the motor control and cause many different types of problems which may require some troubleshooting. Loss of Phase Voltage One of the common problems encountered while diagnosing a motor for an electric m
